The Third Generation LGM-30 Minuteman, first flown in 1961 was developed to replace the hazards inherent in the caustic, volatile liquid-fuel systems of the Atlas and Titan ICBMS. It took 15 minutes to pump 249,000 pounds of propellant aboard the "quick firing" Atlas F. It was dangerous work. Four Atlas silos were destroyed when propellant-loading exercises went awry. Two Titan I silos also met a similar fate. The Minuteman had two innovations that gave it a long practical service life: a solid rocket booster, and a digital flight computer. This computer was one of the very first recognizably modern embedded systems. The solid rocket booster made the Minuteman faster to launch than other ICBMs, which used liquid fuels.
